The FSS includes a dielectric having an arbitrary permittivity and a thickness, a loop gap including a gap and arranged on an upper surface of the dielectric, a patch arranged inside the loop gap, and a cross strip arranged on a lower surface of the dielectric.

• H01P 1/20 - Frequency-selective devices, e.g. filters
• H01P 3/08 - MicrostripsStrip lines
• H01Q 15/00 - Devices for reflection, refraction, diffraction or polarisation of waves radiated from an antenna, e.g. quasi-optical devices

Abstract

A method of a terminal may comprise: performing a connection procedure with each of a first network and a second network based on a multi-connectivity function; performing uplink communication with the first network and the second network; calculating a power reduction value of the uplink communication for at least one of the first network or the second network; and deciding whether to perform the uplink communication based on the power reduction value.

IPC Classes  ?

• H04W 52/14 - Separate analysis of uplink or downlink
• H04W 52/24 - TPC being performed according to specific parameters using SIR [Signal to Interference Ratio] or other wireless path parameters
• H04W 52/38 - TPC being performed in particular situations
